905R Line-cardioid Condenser Mini-gooseneck Microphone Description The Astatic 905R is a line-cardioid, quick-mount, miniaturegooseneck condenser microphone designed for speech and vocal pick-up. The line-cardioid polar pattern (LocusTM technology) is engineered to attenuate unwanted sources outside of the +/- 45 degree acceptance angle while effectively “zeroing-in” on the desired speaker. Astatic’s LocusTM technology provides a significant improvement over other line-cardioid microphones due to diaphragm size and low-noise electronics. The 905R is appropriate for applications such as boardrooms, courtrooms, house of worship and anywhere a gooseneck microphone with optimal distance pick-up is needed. LocusTM technology allows the installer to use the 905R in place of longer miniature-gooseneck microphones without sacrificing performance. It is the perfect solution for the user who prefers not to be distracted by an obtrusive transducer. The 905R is a commercial-grade microphone featuring an all-metal body. The 8mm steel memory-flex gooseneck and ultra-quiet movement provide for worry-free, life-long microphone operation. Special attention has been taken to design the 905R with improved RF immunity to greatly reduce susceptibility to radio interference from GSM based cell phones, PDA/cell phones with walkie-talkie capability and other similar devices. Features • Line-cardioid polar pattern • RF (radio frequency) resistant architecture • 8mm flex pipe with strong positioning memory and silent operation • Quick-mount format • Balanced, transformerless output circuitry • Non-reflective matte-black finish • Included XLR-F type locking flange mount • Included windscreen
FM-2A Locking Flange Mount Installation 1. Mark the center of the mounting location. Be sure to check the underside of the surface for obstructions. 2. Using a 7/8" hole saw or drill bit, cut the centered hole for the cable and bottom of the mount to pass through the surface. 3. Fit the mount into the hole so that the flange sits flat on the surface. Mark the three mounting holes around the flange. 4. Remove the mount from the hole and pre-drill the marked mounting holes for screws appropriate for the installation. 5. Make all final audio connections to the XLR connector. 6. Mount the FM-2A to the surface.
